Add filters (background blur, etc) to your webcam on Linux.

Last update: Dec 14, 2022

Overview

webcam-filters

Add filters (background blur, etc) to your webcam on Linux.

Video conferencing applications tend to either lack video effects altogether or support only a limited set of capabilities on Linux (e.g. Zoom [1], Google Meets [2]).

Goal here is to provide a virtual webcam via v4l2loopback with a common set of filters that can be used everywhere.

Usage

Passthrough (no-op):

$ webcam-filters --input-dev /dev/video0 --output-dev /dev/video3

Blur background:

$ webcam-filters --input-dev /dev/video0 --output-dev /dev/video3 --background-blur 150

Dependencies

Other than the Python dependencies that can be automatically installed by Pip, there are a few system dependencies that require manual attention.

v4l2loopback

v4l2loopback kernel module is required to emulate a virtual webcam. See your distro's docs or v4l2loopback on how to install and set it up (e.g. https://archlinux.org/packages/community/any/v4l2loopback-dkms/).

You'll probably want to create at least one loopback device (that's persistent on boot):

$ sudo tee /etc/modprobe.d/v4l2loopback.conf << "EOF"
# /dev/video3
options v4l2loopback video_nr=3
options v4l2loopback card_label="Virtual Webcam"
options v4l2loopback exclusive_caps=1
EOF
$ sudo modprobe v4l2loopback
$ v4l2-ctl --device /dev/video3 --info

Gstreamer

gstreamer-1.0 (e.g. https://archlinux.org/packages/extra/x86_64/gstreamer/)
gst-plugins-base (e.g. https://archlinux.org/packages/extra/x86_64/gst-plugins-base/)
gst-python (e.g. https://archlinux.org/packages/extra/x86_64/gst-python/)
gst-plugins-good (e.g. https://archlinux.org/packages/extra/x86_64/gst-plugins-good/)

Installation

You can either use pipx or pip. Pipx is recommend to keep dependencies isolated.

Latest stable:

$ pipx install --system-site-packages webcam-filters
$ # Or
$ pip install --user webcam-filters

Latest pre-release:

$ pipx install --system-site-packages --pip-args='--pre' webcam-filters
$ # Or
$ pip install --user --pre webcam-filters

Git:

$ url="git+https://github.com/jashandeep-sohi/webcam-filters.git"
$ pipx install --system-site-packages "$url"
$ # Or
$ pip install --user "$url"

[1]	Zoom desktop client supports background blur as of version 5.7.6. Zoom on web does not.

[2]	Google Meets supports background blur only on Chrome.

Hardware acceleration does not work with the radeonsi driver

Hi :wave:

When I try to use --hw-accel vaapi the GStreamer pipeline does not run. I don't know if I miss something or if some feature is missing (NYI?) in the driver...?

The last line then repeats... Any idea? (Maybe the line ending with VPP does not support global alpha blending shows the problem)

@hsanjuan creating a new issue for this.

I don't see libgstpython.so being loaded, which means none of Python plugins also get loaded. Normally, it looks something like this:

The only thing I can think of is libgstpython.so isn't in a path that GStreamer looks for plugins by default. What happens if you add /usr/lib64/gstreamer-1.0/ to GST_PLUGIN_PATH?

GST_PLUGIN_PATH="/usr/lib64/gstreamer-1.0:$GST_PLUGIN_PATH" GST_DEBUG=GST_PLUGIN_LOADING:4,pyplugin:6 webcam-filters --background-blur 50 ...

Running Debian bullseye here, with python 3.9 and gstreamer 1.18.4 (though python3-gst 1.18.3). When I try to start things up (after creating a v4l2loopback device per the README, at /dev/video11):

numpy_where element does not negoitate cap correctly

As stated in #3, I have a problem where the command, when launched with some parameters for resolution / framerate, exits after one second without showing any error message. Example:

$ webcam-filters --input-dev /dev/video0 --output-dev /dev/video3 --background-blur 150
Selectd input: media-type=image/jpeg, width=1280 height=720 framerate=30/1

(python3:125359): GStreamer-CRITICAL **: 20:04:27.678: The created element should be floating, this is probably caused by faulty bindings

$

Actually, at least with my webcam (a Logitech HD Pro C920), the only working parameters are when setting the resolution / framerate to 1920x1080 at 30 FPS (image/jpeg).

Just tried at the moment to run it with the env variable GST_DEBUG=1 and I get this error just before it gives back the prompt:

Release notes

Dropped Python3.6 support

Some relatively minor fixes and improvements. The most significant update (and the reason for the major version bump) is that Rich has dropped Python3.6 support.

Fixed

Reversed pre and code tags in base HTML format Textualize/rich#2642

Improved detection of attrs library, that isn't confused by the presence of the attr library.

Added

Add type annotation for key_separator of pretty.Node Textualize/rich#2625

The FORCE_COLOR edition

NOTE: 12.6.0 may be the last version to support Python3.6. The next version will be 13.0.0, and will be Python3.7+

[12.6.0] - 2022-10-02

Added

Parse ANSI escape sequences in pretty repr Textualize/rich#2470

Add support for FORCE_COLOR env var Textualize/rich#2449

Error when trying to start

Hello. When I try to start webcam-filters, I get this error:

# webcam-filters --input-dev /dev/video0 --output-dev /dev/video3
Selected input: media-type=image/jpeg, width=1280 height=720 framerate=30/1
Error from /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Cannot identify device '/dev/video3'.

I haven't got video3 device, so error isn't that device is busy. Starting this with different outputs has no effect:

# webcam-filters --input-dev /dev/video0 --output-dev /dev/video10
Selected input: media-type=image/jpeg, width=1280 height=720 framerate=30/1
Error from /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Cannot identify device '/dev/video10'.

I sure that my camera is video0. I installed webcam-filters via pipx, but using nix doesn't fix this error. I have satisfied all dependencies. I use Ach Linux with

# uname -a
Linux arch 5.10.70-1-lts #1 SMP Thu, 30 Sep 2021 09:43:10 +0000 x86_64 GNU/Linux

How can I fix this error? Thanks for your help.

P. S. Sorry for my english, I'm from another county.

Caps object is not iterable

I tried different devices but always the same result. Anything else I can check?
